PUMP.

pasarse.

To all whom t may concern: i Be it known that I, WAYNE W. BLAoK- BURN, acitizen of the United States, residing at St. Petersburg, in the countyof Pinellas and State of Florida, have invented certain new and usefulImprovements in Pumps, 0f which the following is a specification.

My invention relates to pumps and more particularly to that type whereina turbine is employed preferably for dredging purposes. l The primaryobject of my invention resides in the provision of an improved meansassociated with the blades of the fan or turbine for causing the liquidthat is being pumped to pass directly through the fan during theoperation thereof thus increasing the efficiency of the pump, said meansalso serving another purpose, that of preventing the throwing of thewater laterally from the blades as well as incidentally serving thepurpose of increasing the eciency of the joint between the sections ofthe pump cylinder.

A. further object of my invention resides in the provision of a deviceof the character described that is simple in construction, efficient inoperation and one that can be manufactured and placed on the market at aminimum cost.

Other objects as well as the nature, characteristic features and scopeof my invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings andpointed out in the claim forming a part of this specification.

ln the drawing Figue l is a side elevational view of my invention Fig. 2is a longitudinal central sectional view of the pump cylinder showingthe fan positioned therein; and

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2 inthe direction in which the arrow points.

Referring more particularly to the drawings in which similar referencenumerals designate like or corresponding parts throughout the differentviews, I provide a pump cylinder formed preferably of two conical shapedsections l and 2, said sections having flanges 3 projecting from theirenlarged ends for faciliating the connection of the sections through themedium of fasten- Specification of Letters Patent.

and inlet being faciliated through the medium of a collar 6. The inletis controlled through the medium of a check valve 7 associatedtherewith. The section 2 is provided with an opening 8 having a col lar9 formed thereabout, the latter receiving an outlet pipe 10, preferablyin screwthreaded engagement with the coil.

In order to support the inlet and consequently the pump cylinder, I haveprovided standards 1l and 12, the standard 1l having an openingtherethrough for supporting a portion of the inlet 5 as illustrated toadvantage in the drawing. The opposite end of the cylinder or section 2has its apex rigidly supported in the combination bearing and stuffingbox. provided in the upper end of the standard 12 and includespreferably an inwardly eX- tending recess 13 having packing material 14therein, the bottom of the recess having an opening 15 formed therein. f

ln order to create a vacuum within the cylinder and consequently drawliquids thereinto through the inlet and force them through the outlet,preparatory to the securing of the sections l and 2 of the cylindertogether, I have rotatably` mounted in the opening l5 and in the apex ofthe section 2, a shaft 16, the inner end of which terminatesapproximately in a plane in alinement with the joint formed at the baseof the sections 1 and 2, and which shaft has rigidly mounted thereon myimproved fan or turbine 17. In this instance the fan includes a collarhaving a plurality of blades 18 proj ecting radially therefrom, theterminals of This arrangement is` the blades having secured thereto aring or shroud 19, formed preferably of brass, through the medium ofsuitable securing elements 20. This ring incidentally forms theessential part of this invention and is arranged in close relation withthe point of juncture of the sections l and r2. By this arrangement itis readily apparent that the water or other liquid being drawn throughthe cylinder will be consequently forced to pass through the propelleritself, thus increasing the efficiency of the operation of thearrangement. lt will also be noted that the water will not be thrownagainst the point of juncture of the sections and as a affected. l

In order to rotate the fan and consequently create a suction within thecylinder which naturally draws liquid into the inlet and forces itthrough the outlet, I have mounted a gear 21 on the free projecting endthereof, said gear being in mesh with a smaller gear 22 carried on therotating shaft 23 of a motor 24, 'the latter constituting a suitablesource of power.

Although I have shown and described the preferred embodiment of myinvention `I de sire to beunderstood that I am not to be limited to theeXact details shown, however, I desire that great stress be laid uponthe arrangement of the means as associated with the fan for performingthe dual purpose of increasing the eiiiciency of the fan as well asproviding a means for protecting the joint betweenthe tWo sections ofthe cyiinder. These sections as is obvious can be detached when it isdesired to clean the cylinder on the interior thereof. l/Vhen startingthe pump it is rst necessary-to fill the same with water so that whenthefan is rotated it will cause a suction throughthe inlet, which suctionwill incidentally draw the water into the cylinder through the inletanddischarge it through the outlet.

From the above description taken in connection -with the accompanyingdrawings, it can easily be seen that I have provided a device that issimple infconstruction, containing but a few simpleparts that can becheaply -manufactured and assembled and when vassembled can be placedupon the market and sold at a minimum cost.

@It will be understood that the abovefdescription and accompanyingdrawings conv prehend only the preferred embodiment of my invention andthat various minor changes in detail of construction, proportion andarrangement of the parts may be made within the scope ofthe appendedclaim and without sacrificing any of the advantages of my invention.V

I-Iaving thus fully described my invention, what I claim as new anddesire to secure by Letters Patent, is

A pump comprising in combination With spaced standards having openingstherein, a cylindercoinposed of twoseparahle coni cal sections, eachsection being provided on its largest diameter with a flange extendingoutwardly therefrom and the smaller ends terminating` in cylindricalextensions-adapted to be received in the openings `in the standards,means passing through the flanges for securing the sections together,said cylinder being formed interiorly with a bearing surfaceat'thejuncture of the two sections, a rotatable shaft passing throughthe cylindrical eXtension'on one section and projecting into thecylinder, an impeller mounted upon the inner end of the shaft, saidimpeller being provided circumferentiaily with a shroud adapted torotate inthe bearing surface formed at the-juncture of the sections andthus serve tofsupport the shaft at the impeller end, means for rotatingthe shaft and therefrom 'the impeller, and inlet and out ports.

In testimony whereof I aixmy signature in presence of two witnesses.
